However, as described above, only methoxy groups are known as substituent groups for the aromatic group rings of quinolinone derivatives.

Additionally, U.S. Pat. No. 5,378,694 (corresponding to WO 92/04,328 and Japanese Patent Application, Second Publication No. Hei 6-502,845) describes quinolinone derivatives having a carbonyl group as the 3-position substituent group and a hydroxyl group or an alkoxy group as the 4-position substituent group, and the anti-viral activities and anti-hypertension activities of these compounds.

Additionally, U.S. Pat. No. 5,412,104 (corresponding to WO 92/04327 and Japanese Patent Application, Second Publication No. Hei 7-110,853) describes quinolinone derivatives having a substituent group containing a carbonyl group as the 3-position substituent group and an alkoxy group, a carbonyloxy group or an amino group as the 4-position substituent group, and the anti-viral activities of these compounds; European Patent No. 459,561 A2 discloses 2,4-dioxotetrahydroquinoline derivatives wherein the 3-position substituent group is a substituent group containing a carbonyl group and the 4-position group is a variable 4-ketone.

European Patent Application, Publication No. 481,676 A1 discloses a quinolinone derivative having an aromatic group with a substituent group as the 3-position substituent group and a hydroxyl group as the 4-position substituent group; U.S. Pat.

No. 4,127,547 discloses a quinolinone derivative having a sulfonyl group as the 3-position substituent group and a hydroxyl group as the 4-position substituent group.

European Patent Application, Publication No. 685,466 A1 discloses a quinolinone derivative having a sulfide group as the 3-position substituent group and a hydroxyl group as the 4-position substituent group, and WO 96/04288 discloses 5,7-dimethyl-4-hydroxy-2(1H)-quinolinone and 5,7-dichloro-4-hydroxy-2(1H)-quinolinone.

Furthermore, U.S. Pat. No. 5,179,107 and U.S. Pat. No. 5,190,956 abstractly describe an extremely wide range of quinolinone derivatives having substituent groups on the aromatic group ring and having oxygens directly bonded to the 3- and 4-positions. However, the U.S. patents do not disclose quinolinone derivatives having a substituent group, such as an amino group or a nitro group, bonded to the 7-position which the present invention provides.

These U.S. patent publications disclose quinolinone derivatives having the characteristic that the substituent groups at the 3- and 4-positions are identical substituent groups, and disclose that these have anti-viral activity. However, the U.S. patents disclose neither quinolinone derivatives having an amino group bonded to the 7-position nor their anti-allergic activities which are the objects of the present invention.

On the other hand, while numerous anti-allergic agents effective against only immediate type allergies (i.e. I-type allergies) are known, there are almost no reports of anti-allergic agents effective against delayed type allergies. However, of the various types of allergic diseases, the delayed type allergies contribute to the intractable allergic diseases, so that steroids which are effective against delayed type allergies are used clinically.

Although steroids offer strong treatment effects, they also have serious side effects such as digestive ulcers, susceptibility to infections, psychological disturbances, steroidal glycosuria, hirsutism, moonface, osteoporosis wherein the bones become brittle, and obesity. For this reason, the clinical use of steroids must be tightly restricted, and requires the close supervision of physicians.

Thus, steroids are largely used as external medications primarily for light allergic skin diseases, but while their effectiveness against generalized allergic diseases, especially delayed type allergies, is acknowledged, their use is currently tightly restricted, so that the development of a medication which is effective against both immediate type and delayed type allergies while having few side effects has been desired.

As described above, quinolinone derivatives having a derivative of an amino group as a substituent at the 7-position and 7-nitroquinolinone derivatives which are synthetic intermediates of the former have not been known. Furthermore, the facts that 7-aminoquinolinone derivatives and physiologically acceptable salts thereof offer anti-allergic agents which are effective against immediate type allergic diseases and delayed type allergic diseases while having few side effects have not been known.

SUMMARY OF THE INVENTION

The object of the present invention is to offer new nitroquinolinone derivatives, aminoquinolinone derivatives synthesized from these nitroquinolinone derivatives, and physiologically acceptable salts thereof, as well as to offer an extremely safe medication having these aminoquinolinone derivatives and physiological acceptable salts thereof as active ingredients, especially anti-allergic agents which are effective against immediate type allergic diseases and delayed type allergic diseases.

As a first step, 4-nitroanthranilic acid is acetylated to give compound (2). The reaction may be carried out by making use of usual acetylating agent, for example, acetic anhydride or acetyl chloride. The reaction may be carried out at a temperature of from 0 to 120°, preferably from 60 to 100°. The reaction time varies depending on acetylating agent to be used and reaction temperature, generally from 0.5 to 3 hours. Though the reaction can be carried out without a substance to accelerate the reaction, a basic substance may be used as an accelerator. Amine is preferable as a basic substance, for example triethylamine, pyridine and the like.

Next, as a second step, alkylation of the thus obtained compound (2) is carried out, making use of alkyl halide as an alkylating agent. Preferred examples of the base to be used include inorganic salts such as sodium bicarbonate, sodium carbonate, potassium carbonate and the like and alcoholate bases such as sodium ethoxide, potassium t-butoxide and the like and sodium hydride. The reaction may be carried out in a solvent. Preferred examples of the solvent include hydrocarbones such as benzene, toluene and the like, ether solvents such as diethyl ether, tetrahydrofurane, 1,2-dimethoxy ethane and the like, amide solvents such as N,N-dimethyl-formamide and the like. The reaction may be carried out at a temperature of from 0 to 100°, preferably from 20 to 60°, for a period of generally from 1 to 5 hours. In the case of R₁ is hydrogen, following cyclization reaction may be carried out without performing the alkylation reaction described above.

Next, as a third step, the thus obtained compound (3) is subjected to cyclization reaction, affording compound (4). This reaction is performed by treating compound (3) with a basic substance in organic solvent. Preferred examples of the base to be used include alcoholate bases such as sodium methoxide, sodium ethoxide, potassium t-butoxide and the like, sodium hydride, potassium hydride, lithium diisopropylamide, lithium bis(trimethylsilyl)amide and the like. The reaction may be carried out in a solvent. Preferred examples of the solvent include hydrocarbones such as benzene, toluene and the like, alcohol solvents such as methanol, ethanol and the like, ether solvents such as diethyl ether, tetrahydrofurane, 1,2-dimethoxy ethane and the like, amide solvents such as N,N-dimethylformamide and the like. The reaction may be carried out at a temperature of from -50 to 100°, preferably from 0 to 50°, for a period of generally from 1 to 5 hours.

Next, as a fourth step, the thus obtained compound (4) is subjected to oxidation reaction by performing acyloxylation reaction at 3-position of the compound (4). Preferred examples of the oxidation agent to be used include iodobenzene diacetate and the like. In this reaction, the desired compound can be obtained directly by the reaction with iodobenzene diacetate in a organic acid, but also can be obtained by treating an iodonium compound to be isolated as an intermediate with an organic acid. The reaction may be carried out at a temperature of preferably from 30 to 80°, for a period of generally from 2 to 5 hours.

Next, in order to introduce R₂ group and R₃ group into compound (5), when R₂ group is hydrogen, deacylation reaction is carried out in usual hydrolysis manner, when R₂ group and R₃ group are not hydrogen, alkylation reaction or alkenylation reaction are carried out after introduction of preferable protecting group, then deprotection reaction is performed. Preferred examples of the protecting group to be used include hydroxy protecting group, for example methoxymethyl group. Thus the compounds represented by the formula (II), can be produced.

Next, compound (7) is prepared by performing reduction reaction of nitro group of the obtained compound (6), then compound (8) can be produced by following alkylation reaction or alkenylation reaction or aralkylation reaction. In the case of performing these alkylation reaction or alkenylation reaction or aralkylation reaction, when the compound (7) has hydroxy group at 3-position or 4-position, preferable hydroxy protecting group may be introduce into the compound. This reduction reaction is effected by hydrogenation in an atmosphere of hydrogen gas making use of a metal catalyst in a organic solvent. Examples of the metal catalyst include palladium, platinum and the like catalysts which may be used in an amount of from 1 to 10% by weight based on the compound. The reaction in hydrogen gas may be carried out under a pressurized condition or under normal pressure. The reaction may be carried out at a temperature from 0 to 100°, preferably from 20 to 50°, for a period of generally from 1 to 5 hours. This reduction reaction also can be proceeded, making use of metals such as tin and zinc. Thus the compounds represented by the formula (I) can be produced.

Method: Each of aminoquinolinone derivatives (compound No. 6, 8˜10, 14˜17, 19˜51) were forcibly administered orally at the doses of 1000 and 2000 mg/kg to male ICR mice (body weight is 20˜25 g, 5 mice per one (1) group), using an esophageal sound. After the administration, the animals were kept in cages for 7 days, to observed general symptoms and to count dead animals. Lethal doses (LD50:mg/kg) was extrapolated from the mortality at 7th day after administration.

In result, the LD50 of all compounds were over 1000 mg/kg, and therefore it was clearly shown that the compounds of the present invention, Aminoquinolinone derivatives, have extremely low toxicity.

TEST EXAMPLE 2

Effect on Homologous Passive Cutaneous Anaphylaxis (PCA) Reaction in Rats

We performed this pharmacological test by PCA reaction which was well known screening test for anti-allergic agents in order to demonstrate that the compounds of the present invention, aminoquinolinone derivatives, possess anti-allergic activity. This experimental animal model is caused by immediate type allergic reaction, namely, antigen-antibody reaction. In the following, the method of this pharmacological test will be explained.

Method: Male wistar rats (9 weeks old) were intradermally administered 0.05 ml of anti-serum against dinitrophenylated ascaris (DNP-As) into two sites on the shaved dorsal skin. 48 hours later, aminoquinolinone derivatives (test compounds) suspended in 0.5% methylcellulose (MC) were given orally at a dose of 100 mg/kg to the animals. 1 hour after administration of Test compounds, the animals were induced anaphylaxis by injection of saline (1 ml) dissolving 1 mg of trinitrophenylated ascaris (TNP-As) and 5 mg of Evans Blue into the tail vein of the animals. 30 minutes after induction of anaphylaxis, animals were anesthetized by ether and killed by bleeding, and were flayed dorsal skin. The leakage of dye was assessed by measuring the diameter (mean of shortest and longest diameter) of the blue spot on the inside surface of dorsal skin. As vehicle control group, only 0.5% MC solution was administered orally, and as positive control group, Tranilast suspended in 0.5% MC were administered orally at a dose of 200 mg/kg to the animals with the same method as the test compounds groups. The inhibition (%) of PCA reaction was calculated according to equation 1 and the result was shown in Table 1. Each experimental group consisted of 5 rats.

In the conditions of this experiment, it was considered that the compound, which inhibited PCA reaction by over forty (40) percent against that in vehicle control group, was evidently effective for immediate type allergy.

TEST EXAMPLE 3

Effect on Contact Dermatitis Induced by Picryl Chloride in Mice

We performed this pharmacological test by experimental contact dermatitis model which is well known in order to demonstrate that the compounds of the present invention, aminoquinolinone derivatives, inhibit the delayed type hypersensitization. This experimental animal model which is typical delayed type hypersensitization model, was mainly caused by cellular immune response (Immunology, Vol. 15, P. 405-416, 1968). The delayed type hypersensitization is inhibited by steroid, but can not be effected by known anti-allergic agents. In the following, the method of the pharmacological test will be explained.

Method: Mice, shaved their abdominal skin on previous day, were immunized by applying 0.1 ml of acetone containing 7 mg of picryl chloride to the skin of the abdomen. 7 days after immunization, the thickness of the ear was measured with a dial thickness gauge, then mice were challenged by painting 5 ml of 1% picryl chloride olive oil solution to each side skin of left ear. 24 hours after challenge, the thickness of the left ear was measured again. The compounds of the present invention (test compounds) suspended in 0.5% MC were forcibly administered orally at a dose of 20 mg/kg 12 hours after challenge. As vehicle control group, only 0.5% MC solution was administered orally, and as positive control group, Prednisolone, steroid hormone, was administered orally at a dose of 10 mg/kg and as negative control group, Tranilast was administered orally at a dose of 200 mg/kg. The inhibition (%) against the increase of thickness in vehicle control group was calculated according to equation 2 and 3, the result was shown in table 2. In the conditions of this experiment, it was considered that the compound, which inhibited swelling of the ear by over thirty (30) percent against that in vehicle control group, was evidently effective for delayed type hypersensitization.

It was observed that test compounds effectively inhibit the swelling of the ear by 40 to 55% against that in vehicle control group. Many of the compounds of aminoquinolinone derivatives were equivalent to Prednisolone (inhibition: 53%). In contrast, Tranilast, used widely for allergic disease, did not inhibit delayed type hypersensitization. These results clearly show that the compounds of the present invention, aminoquinolinone derivatives, have exceedingly inhibitory activity against delayed type hypersensitization and are greatly useful anti-allergic agent for serious allergic disease for example delayed type asthma etc.

TEST EXAMPLE 4

Effect of Experimental Immediate and Delayed Type Asthma Model in Guinea Pigs

The asthma is typical allergic disease and we carried out this pharmacological test by experimental asthmatic model in guinea pigs in order to confirm that the compounds of the present invention, compound 21, 41 and 46, suppress immediate and delayed type asthmatic response. In the following, the method of the pharmacological test will be explained.

Method: Male hartley guinea pigs were sensitized by exposured aerosolized ovalbumine (OVA) (1% in saline) for 10 minutes per a day at eight times. The aerosol was generated by an ultrasonic nebulizer (NE-U12, Omuron inc.). One week after final sensitization, the animals were challenged with inhalation of OVA (2% in saline) for 5 minutes. The animals were pretreated with metyrapone (10 mg/kg, i.v.) at 1 and 4 hours before the challenge, and pyrilamine (10 mg/kg, i.p.) at 30 minutes before the challenge airway resistance in the conscious animals were measured for 1 minute with PULMOS-1 (made in Medical Interface Project Station Inc.) at 1 minute, 2, 4, 5, 6, 7, 8 and 23 to 24 hours after the challenge. Compound 21, 41 and 46 (test compound) suspended in 0.5% methylcellulose (MC) solution were given orally at doses of 5, 10 and 20 mg/kg 1 hour before and 3 hours after the challenge. As a positive control group, Prednisolone was given orally at a dose of 10 mg/kg 2 hours and 16 hours before the challenge. As vehicle control group, only 0.5% MC solution was given orally.

The evaluation of the effect of the compounds on immediate and delayed type asthmatic response was undertaken with percentage of change in airway resistance 1 minute after the challenge and the area under the response curve for percentage of change in airway resistance between 4 and 8 hours after the challenge, respectively. The inhibition (%) of the compounds for immediate and delayed type asthmatic response was calculated according to equation 4 and the result was shown in table 3. Each experimental group consisted of 8 guinea pigs.
